In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it’s spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was ‘light as a feather’ and could not be explained by Newton’s Laws. I wanted to find out for myself what I really felt like.

Emily’s Hair
{via Evo Terra}

from the page

What makes Emily unique is that by age three her golden [brown] locks were long enough to be made into a wig for a child with cancer. As Emily states in the video, “just cut some off and give it to a kid”. What an incredible lesson to learn from a 3 year old, when we have lots of something – don’t hold onto it, give it away to someone else who needs it more. Emily James is just your typical little 3 year old princess. She loves nail polish, frilly dresses and when she can get her hands on it, mums lipstick. Her favourite movie is Tangled and she is especially fond of her Rapunzel dolly, which is why ‘Dolly’ got a hair cut too. When Emily said she would let Uncle Matthew cut her hair, she insisted that he would cut ‘Dolly’s’ hair first.

criticaldragon1177, All of those books would make awesome documentaries in the right hands — but if I had to pick one, I would lean towards “Magnificent Principia”. I would love to see more documentaries that went back to some hardcore foundational stuff, as opposed to a touristy overview that focuses on the flashier aspects. Less “Relativity is confusing! Check out this twin paradox!” and more “Here’s the basic chain of reasoning that forced us to realize that there can be no universal time.”
